Woz’s father taught him something else that became ingrained in his childlike, socially awkward personality: Never lie. “My dad believed in honesty. Extreme honesty. That’s the biggest thing he taught me. I never lie, even to this day.” (The only partial exception was in the service of a good practical joke.) In addition, he imbued his son with an aversion to extreme ambition, which set Woz apart from Jobs. At an Apple product launch event in 2010, forty years after they met, Woz reflected on their differences. “My father told me, ‘You always want to be in the middle,’” he said. “I didn’t want to be up with the high-level people like Steve. My dad was an engineer, and that’s what I wanted to be. I was way too shy ever to be a business leader like Steve.”
By fourth grade Wozniak became, as he put it, one of the “electronics kids.” He had an easier time making eye contact with a transistor than with a girl, and he developed the chunky and stooped look of a guy who spends most of his time hunched over circuit boards. At the same age when Jobs was puzzling over a carbon microphone that his dad couldn’t explain, Wozniak was using transistors to build an intercom system featuring amplifiers, relays, lights, and buzzers that connected the kids’ bedrooms of six houses in the neighborhood. And at an age when Jobs was building Heathkits, Wozniak was assembling a transmitter and receiver from Hallicrafters, the most sophisticated radios available.
Woz spent a lot of time at home reading his father’s electronics journals, and he became enthralled by stories about new computers, such as the powerful ENIAC. Because Boolean algebra came naturally to him, he marveled at how simple, rather than complex, the computers were. In eighth grade he built a calculator that included one hundred transistors, two hundred diodes, and two hundred resistors on ten circuit boards. It won top prize in a local contest run by the Air Force, even though the competitors included students through twelfth grade.
Woz became more of a loner when the boys his age began going out with girls and partying, endeavors that he found far more complex than designing circuits. “Where before I was popular and riding bikes and everything, suddenly I was socially shut out,” he recalled. “It seemed like nobody spoke to me for the longest time.” He found an outlet by playing juvenile pranks. In twelfth grade he built an electronic metronome—one of those tick-tick-tick devices that keep time in music class—and realized it sounded like a bomb. So he took the labels off some big batteries, taped them together, and put it in a school locker; he rigged it to start ticking faster when the locker opened. Later that day he got called to the principal’s office. He thought it was because he had won, yet again, the school’s top math prize. Instead he was confronted by the police. The principal had been summoned when the device was found, bravely ran onto the football field clutching it to his chest, and pulled the wires off. Woz tried and failed to suppress his laughter. He actually got sent to the juvenile detention center, where he spent the night. It was a memorable experience. He taught the other prisoners how to disconnect the wires leading to the ceiling fans and connect them to the bars so people got shocked when touching them.
Getting shocked was a badge of honor for Woz. He prided himself on being a hardware engineer, which meant that random shocks were routine. He once devised a roulette game where four people put their thumbs in a slot; when the ball landed, one would get shocked. “Hardware guys will play this game, but software guys are too chicken,” he noted.
During his senior year he got a part-time job at Sylvania and had the chance to work on a computer for the first time. He learned FORTRAN from a book and read the manuals for most of the systems of the day, starting with the Digital Equipment PDP-8. Then he studied the specs for the latest microchips and tried to redesign the computers using these newer parts. The challenge he set himself was to replicate the design using the fewest components possible. Each night he would try to improve his drawing from the night before. By the end of his senior year, he had become a master. “I was now designing computers with half the number of chips the actual company had in their own design, but only on paper.” He never told his friends. After all, most seventeen-year-olds were getting their kicks in other ways.
On Thanksgiving weekend of his senior year, Wozniak visited the University of Colorado. It was closed for the holiday, but he found an engineering student who took him on a tour of the labs. He begged his father to let him go there, even though the out-of-state tuition was more than the family could easily afford. They struck a deal: He would be allowed to go for one year, but then he would transfer to De Anza Community College back home. After arriving at Colorado in the fall of 1969, he spent so much time playing pranks (such as producing reams of printouts saying “Fuck Nixon”) that he failed a couple of his courses and was put on probation. In addition, he created a program to calculate Fibonacci numbers that burned up so much computer time the university threatened to bill him for the cost. So he readily lived up to his bargain with his parents and transferred to De Anza.
After a pleasant year at De Anza, Wozniak took time off to make some money. He found work at a company that made computers for the California Motor Vehicle Department, and a coworker made him a wonderful offer: He would provide some spare chips so Wozniak could make one of the computers he had been sketching on paper. Wozniak decided to use as few chips as possible, both as a personal challenge and because he did not want to take advantage of his colleague’s largesse.
Much of the work was done in the garage of a friend just around the corner, Bill Fernandez, who was still at Homestead High. To lubricate their efforts, they drank large amounts of Cragmont cream soda, riding their bikes to the Sunnyvale Safeway to return the bottles, collect the deposits, and buy more. “That’s how we started referring to it as the Cream Soda Computer,” Wozniak recalled. It was basically a calculator capable of multiplying numbers entered by a set of switches and displaying the results in binary code with little lights.
When it was finished, Fernandez told Wozniak there was someone at Homestead High he should meet. “His name is Steve. He likes to do pranks like you do, and he’s also into building electronics like you are.” It may have been the most significant meeting in a Silicon Valley garage since Hewlett went into Packard’s thirty-two years earlier. “Steve and I just sat on the sidewalk in front of Bill’s house for the longest time, just sharing stories—mostly about pranks we’d pulled, and also what kind of electronic designs we’d done,” Wozniak recalled. “We had so much in common. Typically, it was really hard for me to explain to people what kind of design stuff I worked on, but Steve got it right away. And I liked him. He was kind of skinny and wiry and full of energy.” Jobs was also impressed. “Woz was the first person I’d met who knew more electronics than I did,” he once said, stretching his own expertise. “I liked him right away. I was a little more mature than my years, and he was a little less mature than his, so it evened out. Woz was very bright, but emotionally he was my age.”
